Make sure this load center is just like that.

### ⭐⭐⭐⭐⭐ Genuine item, works fine, came without package.
*by K***E on June 3, 2023*

These are the recent (I've gotten breakers manufactured late 22 and early 23) versions of the plug on neutral breaker from Siemens. They work fine (I tested them with the Klein arc tester) and don't trip with drills and even old vacuum cleaners. What threw me is that they came loosely packaged in a plain paper bag. A call to Siemens confirmed they are genuine breakers. I finally realized, from looking at eBay listings, what the sellers are doing is buying the breakers in bulk, say a box of 100 breakers, then selling them individually. As long as they are storing the breakers responsibly (not in extreme heat or moisture conditions) this is fine.
